Description/Abstract

The work contained herein constitutes a report of the “Beyond the StandardModel” working group for the Workshop “Physics at TeV Colliders”,Les Houches, France, 26 May–6 June, 2003. The research presentedis original, and was performed specifically for the workshop.Tools for calculations in the minimal supersymmetric standard modelare presented, including a comparison of the dark matter relic densitypredicted by public codes. Reconstruction of supersymmetric particlemasses at the LHC and a future linear collider facility is examined. Lessorthodox supersymmetric signals such as non-pointing photons and Rparityviolating signals are studied. Features of extra dimensional modelsare examined next, includingmeasurement strategies for radions andHiggs’, as well as the virtual effects of Kaluza Klein modes of gluons.An LHC search strategy for a heavy top found in many little Higgsmodel is presented and finally, there is an update on LHC Z? studies
